I don't think the question is be asked because the OP feels he is owed something.

It's more of a question into the mind of an artist.

I wonder the same thing all the time. But it's not because I feel I'm owed.

It's because people don't understand that an artist who lives and breathes music and is constantly in the studio has no material to put out.

Look at artists like Neil Young, they just released music non-stop. Some is great, some isn't so good.

But they're artists so they're experimenting and recording.

Only reason to not release the music is if you're over-protective of your track record I guess.
